Well, when my husband built me this pc he bought a program called deepfreeze and everytime my puter is rebooted anything that has been downloaded, installed, etc. is wiped off and the computer is booted in the exact state in which it was "frozen." I have to boot thawed in order to have anything stick... kind of can be a pain but is a nice safety net to. There was a learning curve for me at first but I haven't had any major problems and have adjusted the way I work. I was having too much stress over malware

and this has made my life much less stressful now that I have adjusted... been about 5 months now
